Description

Technical Field

[0001] The invention relates to the technical field of ton bag packaging, in particular to a bag pressing machine used for ton bag packaging. Background Art

[0002] Bag presses are used to compress ton bags. Such bag presses usually have a powerful pressure system that can generate enough pressure to compact the materials in the ton bags, thereby reducing their volume for easy storage and transportation.

[0003] The Chinese patent with announcement number CN111169678A discloses a bag pushing and pressing machine for logistics packaging, which includes side panels, a controller, a rear baffle, a bag placing plate groove, a base, a pushing structure, a forward and reverse reduction motor, a motor controller, a shielding plate, and a threaded rod. The lower ends of both sides of the shielding plate are welded with side panels. The present invention ensures that the material inside the packaging bag at the highest point will not be pressed by the pressing block to apply pressure to the material inside the packaging bag due to the continued downward movement of the support plate, causing the material to deform. When the support plate continues to move downward, it will drive the part of the pushing support rod structure that is in contact with the packaging bag to move downward until the pressing blocks are all in contact with the packaging bag and the internal gas is completely squeezed out. Then, the packaging bag is sealed, so that a large amount of gas inside the packaging bag can be discharged, thereby reducing the space occupied by the gas inside the packaging bag. Moreover, through its structure, the gas in the bag of materials of different shapes can be squeezed, making it more widely usable.

[0004] With regard to the above-mentioned related technologies, the above-mentioned bag press is used to pressurize ton bags. In the prior art, the staff uses the cooperation of the inner groove threaded rod and the push rod structure to apply pressure to the ton bag so that the air inside the ton bag is squeezed out. However, when the ton bag is loaded, a mixture of material dust and air exists inside the ton bag. If the mixed gas is directly squeezed out, it will cause dust pollution in the surrounding environment, which is not conducive to the packaging work of the ton bag and will also affect the health of the staff.

[0014] By adopting the above technical solution, when clamping the mouth of the ton bag, the staff places the mouth of the ton bag in the clamping groove, and then uses the rotating assembly to drive the rotating disk to rotate. By cooperating with the driving arc groove and the limiting groove, several driving columns are driven to move simultaneously in a direction away from the center of the rotating disk, driving the clamping plate to move until the mouth of the ton bag is clamped between the clamping plate and the side wall of the clamping groove, thereby achieving the effect of clamping the mouth of the ton bag.

When the moving seat moves, the pay-off wheel rotates and continuously pays out the wire. After the mouth of the pressure bag is tied for several turns, the tightening motor is started, and the pay-off wheel is driven to rotate in the reverse direction through the ratchet ring to pull the tying wire to tighten the mouth of the pressure bag. Finally, the tying wire is cut with a tool, and the two ends of the tying wire are knotted to close the mouth of the ton bag.

[0022] By adopting the above technical solution, the ton bag is heavy with the material inside, which is not conducive to placing the ton bag in the bag pressing machine. The staff uses the sling to place the ton bag on several conveyor rollers, and starts the conveying motor to make several conveyor rollers rotate synchronously, so as to convey the ton bag to the bottom of the pressing table. After the ton bag is compressed, the ton bag is moved out of the bag pressing machine, realizing the conveyance of the ton bag.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When pressing the bag, the staff uses the clamping assembly to open the mouth of the ton bag, and then uses the lifting parts to drive the pressing platform down, so that the air extraction pipe enters the ton bag, and starts the air pump. As the pressing platform continues to descend and the pressing platform continues to press the ton bag, the mixed gas in the ton bag enters the installation tank through the air extraction pipe, and the dust is filtered through the filter element, and the pure air is discharged. The dust is retained in the powder storage tank, and finally the ton bag mouth is tied with the bundling assembly, achieving the effect of the bag press compressing the ton bag. By setting up the dust removal assembly, the staff can extract and filter the mixed gas inside the ton bag while compressing the ton bag. Compared with the existing technology, this reduces the possibility of the mixed gas filling the surrounding environment when the ton bag is compressed, reduces the environmental pollution caused by the ton bag packaging work, and also protects the health of the staff;

[0025] 2. When clamping the mouth of a ton bag, the staff will place the mouth of the ton bag in the clamping groove, and then use the rotating assembly to drive the rotating disk to rotate. Through the cooperation of the driving arc groove and the limiting groove, several driving columns are driven to move in the direction away from the center of the rotating disk at the same time, and the clamping plate is driven to move until the mouth of the ton bag is clamped between the clamping plate and the side wall of the clamping groove, thus achieving the effect of clamping the mouth of the ton bag;

[0026] 3. When tying ton bags, the staff starts the lifting cylinder to drive the lifting ring plate down to detach from the storage slot, then ties one end of the tying wire on the pay-off wheel to the take-up wheel, and uses the driving assembly to drive the moving seat to move. When the moving seat moves, the pay-off wheel rotates and continues to pay out the wire. After the bag mouth is tied for several turns, the tightening motor is started, and the pay-off wheel is driven to rotate in the reverse direction through the ratchet ring to pull the tying wire to tighten the bag mouth. Finally, the tying wire is cut with a tool, and the two ends of the tying wire are knotted to close the bag mouth. Finally, the clamping assembly is released to achieve the tying of the ton bag;

[0027] 4. When driving the moving seat to move, the staff starts the driving motor to drive the friction wheel to rotate, and applies pressure to the clamping block through the force of the clamping spring, so that the friction wheel presses against the side wall of the moving groove. Through the friction force, the rotating friction wheel drives the moving seat to move.

At the same time, the mixed gas is pulled by the air pump 51 and filtered by the filter element 53. The dust falls into the powder storage tank 54, and the clean air is discharged, achieving the effect of filtering the mixed gas.

[0056] The implementation principle of a bag pressing machine for ton bag packaging in the embodiment of the present application is as follows: when packaging ton bags, the staff uses a sling to place the ton bag on the conveying roller 21, starts the conveying motor 22, drives the conveying roller 21 to rotate, and conveys the ton bag to the bottom of the pressing platform 11, places the bag mouth of the ton bag in the clamping groove 112, starts the rotating motor 61, rotates the rotating gear 62, drives the rotating disk 31 to rotate, and makes a plurality of driving columns 33 move toward a position away from the center of the rotating disk 31 at the same time, drives the clamping plate 32 to move until the bag mouth of the ton bag is clamped between the clamping plate 32 and the side wall of the clamping groove 112, then starts the lifting member 12, drives the pressing platform 11 to descend, and the exhaust pipe 521 enters the ton bag. During the compression of the ton bag under the influence of the pressing platform 11, the air pump 51 is started at the same time, and the mixed gas in the ton bag enters the installation tank 52 through the exhaust pipe 521 and is restricted by the limiting plate 523 The dust is blocked and dispersed, and at the same time, it is pulled by the air pump 51, and the mixed gas is filtered by the filter element 53, and the dust falls into the powder storage tank 54, and the clean air is discharged. At this time, negative pressure is formed inside the ton bag, and the bag mouth of the ton bag shrinks slightly. The pressing table 11 rises a certain distance, and the lifting cylinder 42 is started to drive the lifting ring plate 41 to descend and disengage from the storage groove, and the tying line on the wire-releasing wheel 43 is tied to the wire-receiving wheel 44, and the driving motor 71 is started to rotate the friction wheel 72, and the moving seat 45 is driven to move along the lifting ring plate 41. While driving the wire-releasing wheel 43 to move, the tying line ties the bag mouth of the ton bag for several circles, and then the tightening motor 46 is started to make the wire-releasing wheel 43 rotate in the opposite direction, so that the tying line tightens the bag mouth of the ton bag, cuts the tying line and ties the tying line head to close the bag mouth of the ton bag, releases the clamping component 3, and at the same time uses the conveying component 2 to convey the ton bag out of the bag pressing machine, thereby realizing the compression and packaging of the ton bag.

[0057] By setting up the dust removal component 5, the staff can extract and filter the mixed gas inside the ton bag while compressing the ton bag. Compared with the existing technology, this reduces the possibility of the mixed gas spreading to the surrounding environment when the ton bag is compressed, reduces the environmental pollution caused by the ton bag packaging work, and protects the health of the staff.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
